1 on 1 Interview
Please describe the interview / hiring process.
“How many hairstylists or barbers do you estimate there are there in this city? Explain your logic/assumptions.”

Answer: Explain the logic based on the population of the city, average number of cuts people have per year, number of cuts one barber can do per year, and thus how many that implies there must be. (i.e. 2 million people, each get an average of 4 cuts per year, which results in 8 million cuts per year. Each barber works an average of 8 hours per day, times five days per week, times fifty weeks per year equals 2,000 hours of cutting time per year. Each haircut takes 1 hour. Thus, 8 million haircuts, equal 8 million hours, divided by 2,000 hours per barber requires 4,000 barbers in the city.)
